RDropdownRenderRequest class sealed

Render request containing everything a dropdown renderer needs.

Follows the pattern: context + spec + state + semantics + callbacks + slots + tokens + constraints. Only includes what the renderer actually needs (perf + API stability).

Non-generic by design: Contains only UI data (labels, indices). The component maps value ↔ index internally before calling the renderer.

See docs/V1_DECISIONS.md → "0.1 Renderer contracts".
